Yep, that's me. Sometimes to a fault.
But falling into those first-born tendencies is how I would help my mom when we had my grandparents or other family over for dinner. I'd set the table and take drink orders. Related to the kitchen, I also put away the groceries, probably because I liked restoring order in small ways.
Watching my 5-year-old niece this weekend was like looking into a time-warp mirror. Twice, Milla wanted to set the table and carry people's drinks (for which she solicited orders) to their places.
Also, now that Milla has a brother (6 months old now) and a younger cousin in Cate, she has plenty of opportunities to be bossy and the know-it-all of the group. I'm sure my brother and sister can look at her in those moments and see another version of me.
